Abstract

The utility model relates to a variable structure dual-mode ramjet combustion chamber, which relates to an aeroengine combustion chamber. Including isolation section, concave cavity, sudden expansion section, adjustable variable section, Pioneer hydrogen injection module, kerosene injection module, connecting rod and hydraulic drive; through the hydraulic connecting rod drive, the combustion chamber can be adjusted to make the combustion chamber operate at different flight Mach numbers work in different modes. 2

Description

Technical field [0001] The present invention relates to an aero engine combustion chamber, specifically to a variable structure dual-modal rammer combustion chamber with adjustable combustion chamber profile. Background [0002] When the flying Mach number Ma>3, the performance of the ramjet engine is optimal, wherein the flying Mach number Ma = 3 ~ 6, the sub-combustion ramjet engine performance is better than the super-combustion ramjet engine, and the flying Mach number Ma > At 6 o'clock, the super-fueled ramjejet engine performed better than the sub-combustion ramjet ramjet engine (Weber R J, Mackay J S. An Analysis of Ramjet EnginesUsingSupersonic Combustion[R]. NASA TN 4386，1958)。 For optimal performance, ramjet engines must operate in a dual-mode fashion. In the acceleration process of a hypersonic vehicle with a bimodal ramjet as the propulsion device, the heat release and distribution in the combustion chamber must be adjusted accordingly, so that the engine is co...
